[PATCH AUTOSEL 6.14 03/15] iio: imu: st_lsm6dsx: Fix wakeup source leaks on device unbind

[Sasha Levin <sashal@kernel.org>]

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

[ Upstream commit 4551383e78d59b34eea3f4ed28ad22df99e25d59 ]

Device can be unbound, so driver must also release memory for the wakeup
source.
